Why should the water be softened?
How do I measure the water hardness? Application Water Hardness Test Set
Fill the measuring cup with 5 ml water from the whirlpool. Now add the measuring liquid drop by drop. Shake the liquid after each drop so that the water and the measuring liquid mix. The water turns red. Count the drops you add. As soon as the water turns green, you have determined the degree of hardness. Each drop corresponds to 1 degree of German hardness. If the water in the measuring cup changes colour from red to green with 10 drops, you have a water hardness of 10 degrees German hardness.

Example
You have a water hardness of 30 and want to reduce the water hardness to 12. Your whirlpool has a water volume of 1200 litres.
You then take 2.1 kg and multiply it by 1.2(1200 litres). Result: 2.52 kg. You divide the 2.52 kg by 0.8 kg (weight of the SoftWater Pad) The result is 3.15. In this case you need 3 SoftWater Pads as one pad contains 0.8 kg softener mineral. You can also take 2 SoftWater Pads and soak the SoftWater Pads (when the water hardness no longer decreases) for a few days in distilled water with 30% salt content. This removes the calcium ions from the softener mineral and replaces them with sodium ions. The Pads can then be reused.
What is the ideal water hardness in a whirlpool?
The ideal water hardness is between 7 and 10 degrees of German hardness.
Where should the SoftWater Pads be placed?
A good flow is important for a fast and effective softening of the water with the SoftWater Pads. It is best to place them in the filter chamber. For whirlpools without a filter chamber, the SoftWater Pads should be placed directly on the filter. It may be useful to increase the filter running time during the softening period.
How long does it take to soften the water?
This depends on the water hardness, the number of SoftWater Pads used and the flow rate. It can be from one or two days to two or three weeks.
Can I use the SoftWater Pads more than once?
This is possible. After use, the bags must be placed in distilled water with at least 30% salt content. This regenerates the SoftWater Pads.
How do SoftWater Pads work?
The SoftWater Pads contain a special mineral which is charged with sodium ions. These minerals release sodium ions in the water and absorb calcium ions. This makes the water softer.
I have a water softener at home. Do I still need the SoftWater Pads?
Yes, a domestic water softener can only soften a certain amount of water at once. But never as much as fits in a whirlpool. Once the target water quantity has been reached, the exchanger granulate in the water softener would have to be regenerated. However, since much more water is allowed to run continuously through the water softener, unsoftened water also ends up in the whirlpool after the target water quantity has been reached.
How do I measure the hardness of my water after using the SoftWater Pad?
To measure your current water hardness we recommend the SpaBalancer Total Hardness Test Kit.
